我遵循Kubernetes教程,並在我的MacBook上使用Minikube作爲我的Kubernetes環境。教程中的所有步驟都運行良好,除了使Ingress正常工作(Ingress的教程,我遵循的是:https://cloud.google.com/container-engine/docs/tutorials/http-balancer)。通過Ingress訪問時,出現「301 Moved Permanently」錯誤。Kubernetes/Minikube入口錯誤(301永久移動)
我的環境:
- 的MacBook(MacOS的塞拉利昂,版本:10.12.5(16F73))推薦Minikube
- xhyve司機
- minikube版本:v0.19.0
我使用默認的Ingress控制器(用於minikube的nginx),並且已成功啓用 進入:
minikube addons enable ingress
我再接着在教程中的步驟:
步驟1:部署一個nginx的服務器(成功)
kubectl run nginx --image=nginx --port=80
步驟2a:暴露你的nginx部署爲服務內部(成功)
kubectl expose deployment nginx --target-port=80 --type=NodePort
步驟2b:驗證服務可用:
kubectl get service nginx
輸出:
NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE
nginx 10.0.0.170 <nodes> 80:31635/TCP 7s
從上面的,我知道該服務是正確創建...
第3步:創建一個入口資源(成功)
入口配置YAML(基本-ingress.yaml):
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: basic-ingress
spec:
backend:
serviceName: nginx
servicePort: 80
而現在應用YAML:
kubectl apply -f basic-ingress.yaml
步驟4a:驗證入口
kubectl get ingress basic-ingress
輸出:
NAME HOSTS ADDRESS PORTS AGE
basic-ingress * 192.168.64.37 80 16s
步驟4b:訪問應用程序(* UNSUCCESSFUL *)
教程指出我應該「將我的瀏覽器指向您的應用程序的外部IP地址並查看w eb頁面標題爲「Welcome to nginx!」。
當我指出我的瀏覽器的網站(http://192.168.64.37)是試圖轉換到https這給出了一個錯誤「安全連接失敗」(從Firefox,但在Chrome類似的錯誤)
然而,當我捲曲現場我得到的「301」錯誤:
curl 192.168.64.37
輸出:
<html>
<head><title>301 Moved Permanently</title></head>
<body bgcolor="white">
<center><h1>301 Moved Permanently</h1></center>
<hr><center>nginx/1.11.12</center>
</body>
</html>
我一直在努力,到目前爲止調試這一點,但沒有運氣,但是,我有省下面ided進一步的信息......也許它會在診斷問題有用:
全部入口說明:
kubectl describe ingress
輸出:
Name: basic-ingress
Namespace: default
Address: 192.168.64.38
Default backend: nginx:80 (172.17.0.3:80)

最後一個註釋......當我在基礎中添加「host:」標記時ress.yaml文件,並將basic-ingress.yaml文件中使用的主機名映射到/ etc/hosts中的IP地址(192.168.64.37),然後我就可以使其工作。不知道爲什麼Minikube需要一個「主機」標籤,其中幾乎相同的教程在沒有主機標籤的GCE上運行。
我不相信Minikube默認啓用Ingress - 除非啓用「minikube addons enable ingress」,否則Ingress功能不起作用 –
